LiveCode Forums

To give this topic some much-needed oxygen, I've shared the Quartam JVM External code on github. For now, it's all still in the 'develop' branch as I need to go back in and sort out the windows side. Not to mention add some explanations on how to use it. Anyway, you can take a look at https://github...

I think revEvaluateXPath is a better name for the function: revDataFromQuery in revdb is a different animal.
Someday we can just have 'evaluate xpath theXPath in xml tree theXmlTree'

Thanks for trying and sharing your experiences, Monte.
Maybe one day writing OS X externals can be as easy as iOS externals, with a LiveCode template project
I'll try and build the 'universal' binary of my external on the iMac G5 over the weekend.

I second Monte's suggestion: return a list of matching node (unique) paths.
That way the developer can't forget to free the nodes.
You could of course keep track of them per document and free them along with the doc.

@monte: I could build for i386 but not ppc - also due to a broken pipe. Did you get it running after a re-install?

Jan Schenkel.

@runrevmark: I'll give it another go when I get home this evening and report my findings.
And I will definitely check out the build settings for the rev externals to see what information I can extract from that to get my own external project running.

@runrevmark: I did use that lesson to extract the older SDK's and compilers and add them to Xcode (otherwise I couldn't have tested any of my contributions), but Xcode steadfastly refuses to build my external's project. Then again, I could just be exceptionally thick when it comes to build configura...

Hi Monte,

I'm guessing that means you're not providing ppc/universal builds of those externals then? Actually, if I can convince my iMac G5 to crank out i386/universal builds, then I'll use that machine as it's still running MacOS X 10.4.11 Tiger with Xcode 2.3 - fingers crossed!

Hi all, My attempts to build desktop externals with Xcode 4.6 are proving futile and I no longer have an Intel computer running MacOS X 10.4 Tiger with an older Xcode version (so that I can build universal externals). Is there any chance of getting an update to ExternalsEnvironmentV3 for Desktop, or...

I was being silly when I wrote 'answer ... without messages' as this would lead to much hair-scratching for newer developers - I think it's better to not immediately dispatch messages that aren't specific to the modality chain, and queue them for later delivery. And I specifically use the term modal...

Shouldn't that be instead?

Hmm, it's been a while since I looked into this; and I found a workaround for reading PNG pixel data by tampering with the header and trailer. If my memory serves me well, the core payload for zlib and gzip compression is the same, but they wrap it in different ways. Let me see if I can find some ti...

@runrevmark: if you tell me where to look, I'll see if I can help untangle the Java synchronization stuff

Update: I tweaked the error messages and submitted pull request 74 for this set of new functions.

Cheers,

Jan Schenkel.

@Mark: I haven't yet investigated the matrix code - but once you get the hang of it, it shouldn't be too hard
It's probably bed to split that off into a topic of its own on this forum, with a concrete idea, so others can chip in.
